As answered by people managing Markup.io and Causr.
Causr's answer:
Independent/Fractional Project Managers
Causr's answer:
Most project management tools track tasks. Causr tracks the conversations, decisions, risks, blockers and dependencies that determine whether those tasks are delivered. It keeps project accountability visible instead of buried in spreadsheets, meeting notes and chat threads.
Causr's answer:
Causr focuses on project governance rather than task management. It helps delivery teams identify hidden risks, assign ownership and understand how unresolved issues impact project milestones.
Causr's answer:
Causr is built for Project Managers, Programme Managers, PMOs, Delivery Managers and Product Managers responsible for delivering complex projects with multiple stakeholders.
Causr's answer:
Causr was created after seeing and experiencing the same problem across countless projects: decisions, risks and blockers were documented, but rarely followed through. The goal was to build a platform that makes project accountability impossible to lose. Built for Project Managers, by Project Managers.
